Improvement in plows



UNITED STATES PATEN IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent N o. 113,436, dated April4, 1871.

' certain new and useful Improvements in the Manufacture of Plows, ofwhich the following is a specilication, giving a full, clear, and exactdescription of the construction and oper ation of the same, makingreference to the accompanyin g drawing, in which like letters indicatelike parts.

My invention relates to that class of -plows which have theirwearingsurface of steel, and it consists in a steel plowshare, which isremovable from the land-side bar and mold-board when the share isconstructed having a ange, and the land-side bar is faced with steel,and the forward end of the landiside bar extends under and supports theforward end of the share, substantially as herein shown.

Figure 1 gives a view of a plowshare and land-side bar detached from theland-side bar facing and mold-board. Fig. 2 gives a view of themold-board side of the plow. Fig. 3 gives a view of the land-side sideof the plow.

A is a steel plowshare, having a ange, K, at its forward end. B is theland-side bar,its forward end extending under the forward end of theshare A by the side of the flange K, and a bolt atz secures theland-side bar in its position. The back end of the ange K forms ashoulder, as seen at x.

E is a steel facing of the land-side bar, to

which it is secured by rivets or screwbolts at aan, and its forward endrests against the shoulder x, at the back end of the flange K, and thebreast of the facing fitting under the thin end of the mold-board, asshown, e to e, in Fig. 3; and any proper method of securing the breastof the facing and the shin end of the mold-board together may be used.

W is a steel mold-board, which is secured in position by bolts or rivetsat b b, through lugs or connecting-bars, to which the share A is alsobolted at (t a. More or less bolts, rivets, or lugs may be used, andthey may be in any position securing the parts together.

The iange K is formed on the end of tne 4 share by welding thereto apiece of metal of the shape and form of the liange, Ior a portion of theshare may be bent over the end of the land'side bar, and the iiange mayor may not be so bent or formed as to hook on the under side of theland-side bar, and which is not an essential part of my invention.

' My invention, although seemingly slight, is important, as by its use lam enabled to make a strong plow, of extreme hard-tem pered steel facethroughout the whole wearing-surface, which has not as yet beenaccomplished by any other method of construction. It is well known thatthroughout the West the plow is made of steel, and the mold-boardhardened to the cxtreme hard temper, while the share and laudvside wereleft untempered, by reason th at it is not practicable to hard-tempershares which are welded to a land-side bar, owing to their springing andwarping destroying them for use. By the use of iny improved method ofconstruction the share and land-side bar facing are in separate piecesand removable from the land-side bar-whereas before they were as onepiece-and may be hardened to the extreme hard temper without liabilityof being destroyed by springing or warping.

Having thus set forth my invention, I claim- -In combination, theland-side bar B, steel plate E, mold-board W, share A, and flange K, allas herein set forth.
